Waykar CTH150PD 150-PPD dehumidifier review

The Waykar CTH150PD is the pump-equipped, fixed-vent choice in the CTH-D product group. Its 150-pint label is specified at 95°F/90% RH; the exact ENERGY STAR record reports 49.43 pints/day under Appendix X1. The pump changes installation options, not that rating. It is the only current CTH-D selector in the captured U.S. page with the pump, and its manual gives a maximum vertical lift of 16.4 feet.

Waykar’s exact U.S. page maps selector 47993814155502 to SKU CTH150PD and GTIN 721820975421. I compared its archived page and shared D-family manual with ENERGY STAR record 4591187. The product-page image is the same family view for all three CTH-D selections; it does not show the pump hose or prove which variant is selected.

Use the correct 150-pint comparison

The manual lists 150 pints/day at 95°F/90% RH, 123 at 80°F/80% RH, 75 at 80°F/60% RH, and 50 at 65°F/60% RH. ENERGY STAR Appendix X1 is 49.43 pints/day. That difference is small, but it means the CTH150PD passes a 35-pint standard-condition threshold and misses a strict 50-pint minimum. Do not round 49.43 up for a hard filter. The claimed 150-pint maximum and the 49.43-pint standardized value describe different conditions, not contradictory daily outcomes.

The EPA record gives an IEF of 2.20 L/kWh, 471 kWh annual use, certification, and Most Efficient status. The manual lists 750 W and 7.5 A at 115 V/60 Hz. These figures help compare the exact configuration but do not predict the bill or room performance: humidity, temperature, set point, and run time determine actual use. Against CTH80D and CTH120D, this is the higher-capacity choice and the only pump-equipped current D selector. The CTH150D appears in the manual as a separate non-pump model code, but it is absent from the captured current page’s three selectable SKUs; I do not treat it as this review’s offer or borrow its availability.

Choose a real drain route before buying

The CTH150PD has a 7.1-liter/1.9-gallon tank, larger than the 4.6-liter/1.2-gallon tanks assigned to CTH80D and CTH120D. The manual describes tank-full alert and automatic shutoff. For a low drain, it also supports gravity drainage through the included 3.3-foot hose; the route must run smoothly downhill, with the outlet at least 3.94 inches below the port. This may be simpler than using the pump when a floor drain is nearby.

For a raised destination, the manual specifically identifies CTH150PD as pump-equipped. It includes a 5-meter/16.4-foot pump hose and sets maximum vertical height at 5 meters/16.4 feet. Keep those measurements distinct: hose length is not the same claim as vertical lift, and the manual does not specify a combined horizontal-plus-vertical installation envelope. Plan the route, bends, and destination carefully; a requirement above 16.4 feet vertical is not supported. The manual says to attach the pump hose before activating pump mode, and to check the tank if a full-tank alarm occurs before the pump is enabled. This does not establish bucketless operation or permission to remove the tank.

Controls and fixed outlet

The product page calls this a fixed-vent unit. If you want the automatic up-and-down outlet motion documented for some CTH-B models, this D-coded configuration does not meet that requirement. The manual does document a temperature-responsive Auto Mode that sets 55% RH below 64°F, 50% from 64°F to 77°F, and 45% above 77°F. Auto Mode keeps the fan low and disables manual fan-speed changes; regular Dry Mode offers 30%–80% RH targets in five-point steps and three fan speeds. Other documented functions include a 24-hour timer, restart memory, full-tank protection, and automatic defrost.

ENERGY STAR lists the exact CTH150PD as not connected-capable, so app control is not confirmed. The manual gives a 41°F–90°F operating range, a 54-square-foot minimum room area, and 18 inches of clearance around the cabinet. It also shows caster wheels. The product page does not give a sound-pressure number, dimensions, or dry weight. “Super Quiet” is a product-title claim, not measured noise data. The precise CTH-D page’s detailed text includes a table naming B-code models; I relied on the shared D-family manual and exact EPA record for this assessment rather than transferring those B-code details.

Who should choose the CTH150PD?

Choose it when 49.43 pints/day under Appendix X1 meets your need, the fixed outlet is acceptable, and either tank collection, a lower gravity outlet, or a pump route with no more than 16.4 feet of vertical lift suits the room. It is not a fit for a strict 50-pint standardized minimum, app control, bucketless use, automatic outlet swing, a specified decibel ceiling, or a route beyond the documented lift. If you do not need a pump, compare the CTH150B or CTH150D only by exact model code and separate evidence: a similar capacity label does not make their drainage features interchangeable. Buy by the full CTH150PD code, not by the generic family picture.
